Product EL 38

Thermal class: 220 C

EL 38 is a polyamideimide enamel, with good wire surface, excellent mechanical capability, high heat, and chemical resistance, suitable for 0.05mm and greater diameter wires. It is usually used as a topcoat, during the composite wire enameling. The base coat, to be used with EL 38 is modified polyester (PE), or polyesterimide (PEI) wire enamels. The wires with EL 38, have good performance and freon resistance and are widely used for thermal resistant applications, including transformers and compressors. It can also be used as single coating, thermal class 220. UL listed. EL 38 is suitable for vertical and horizontal enameling processes, can be applied by dies or felt methods of application.
